STATE WATERPROJECT

The California State Water Project (SWP)

is the largest state-built and operated

multipurpose water and power system in

the United States. The 701 miles of canals

and pipelines provide drinking water for

25 million people and irrigation for

750,000 acres of farmland. The SWP also

provides power generation, year-round

recreation, flood protection, and helps

maintain Delta water quality.

California's history, landscape and

economy have been shaped by water.

To address nature's water imbalance

and allow for growth, water has to be

transferred from where it is plentiful

to where it is needed. Californians

provided the solution with passage of

the 1960 California Water Resources

Development Bond Act, which authorized

$1.75 billion for construction of the SWP.

The project was constructed in stages

from north to south. Oroville Dam,

built from 1961 to 1967, is the tallest

dam in the United States (770 feet) and

one of the main sources of hydropower

on the project.

Construction of the Delta pumping

facilities, South Bay facilities, San Luis

Reservoir (built by the U.S. Bureau of

Reclamation and operated by DWR) and

the California Aqueduct was completed

in the late 1960s. The next phase

delivered water over the Tehachapi

Mountains at Edmonston Pumping Plant.

Edmonston was completed in 1973

and has the highest lift per volume in the

world with a single lift of 1,926 vertical

feet and a maximum volume of 4,480

cubic feet per second. The newest facility

of the SWP – the Cherry Valley Pumping

Station on the East Branch Extension –

was completed in 2003.

The SWP has been recognized by the

American Society of Civil Engineers as

one of the outstanding engineering

achievements of the 20th Century.

H Y D R O E L E C T R I C P O W E R

Project hydroelectric plants help keep

water delivery rates to SWP contractors

affordable by producing much of the

electricity needed to pump water. Costs

are also defrayed by pumping during

off-peak hours when electricity is less

expensive and generating power for sale

during periods of high demand when

power is more expensive.
